题目内容
4．I don't think it is _____ useless competition，because it has offered us ____valuable experience for the next competition．（ ）| A． | the； a | B． | an；/ | C． | an； a | D． | a；/ |
分析 我不认为这是一个无用的比赛，因为它为我们为下一场比赛提供了宝贵的经验，
解答 答案：D
a/an是不定冠词，表泛指，an用于元音音素开头的单词前，a用于以辅音音素开头的单词；the是定冠词，用于特指．结合句意：我不认为这是一个无用的比赛，因为它为我们为下一场比赛提供了宝贵的经验，本题第一个空useless/?ju：sl?s/，第一个音素是辅音音素，所以用a 表示一个；第二空 experience经验，是不可数名词，前面不加冠词，故选D．
点评 本题考查的是冠词的用法，要根据句子意思和冠词的用法规律做题，还要注意结合音标作答．
